Is there a way to host a guest network on a repeater router?

I have a network setup with three linksys E2500 routers running shibbys firmware v112 Tomato 1.28. One of the main routers is working as the main router hosting the network, and the other two are working as repeaters (connected to the main as wireless ethernet bridge and resharing the wireless with a virtual acess point). I was able to set the guest network working on the main router, but i also want the repeater routers to host a guest network. I tried the same setup but it did not work. DHCP wont work for the guest network on the repeater routers. From searching online, it seems that it is related with DHCP being disabled for br0 on the repeater routers.

Can anyone tell me how to get this working?

Also, it is not an option for me to change to DDWRT since they currently havent upgraded their release for E2500 to support the 5ghz radio.

Can't have both the main + guest repeated on the same router. A repeater requires the router to be a wifi client and AP simultaneously. Having both a repeater for main + guest would require the router to be 2 wifi clients simultaneously.

I agree you cannot have a repeater router repeat both the main network and the guest network for the same reasons you mentioned. What I want to do is have the repeater router repeat the main network and host a new guest network different from the guest netwok on the main router. I dont care if all guest networks are different and unrelated.

I had that setup with DD-WRT and I don't see why wouldn't work with Tomato. Setup another virtual SSID with another subnet, use Iptables/ebtables rules to setup WiFi as guest if required, and that's it.
